4.15.1 has the issue, 4.14.3 doesn’t.
See from a distance is OK, close enough to a surface rise the issue (as the pictures shows).
Blink occurs during camera moving, if camera stops moving, the crashed image just keep what it looks like.
I really don’t want to go back to 4.14.3 because I find that 4.15.1 is much faster to launch the editor. If this is a bug, is there any walk around before the next release?
